How to create bus from timeseries object including enumerated class?

1) I define an enumerated class BHA **

classdef BHA
   enumeration
      Stationary, Run
   end
end

**** (2) Then I generate a timeseries ****

clear all; close all;
for row = 1:12
   a(:,:,row) = [1;2;3];
   b(:,:,row) = [1;2]*9.8;
   c(:,:,row) = BHA.Stationary; 
end   
HallwaySensonor.a = timeseries(a);
HallwaySensonor.b = timeseries(b);
HallwaySensonor.c = timeseries(c);
save('HallwaySensonor.mat','HallwaySensonor','-v7.3');

*** (3) Now as I try to create the bus, I got the trouble ***

load('HallwaySensonor.mat');
busInfo = Simulink.Bus.createObject(HallwaySensonor);

*** It shows Error using Simulink.Bus.createObject>createBus (line 324) Simulink.Bus.createObject reported the following error when processing the field 'c' in the input structure:

'Invalid value specified for parameter
object.  Value must be a numeric array,
fi object, an enumerated value, or a
scalar structure whose fields contain
valid values.'

Error in
Simulink.Bus.createObject>createObjectFromVarStruct
(line 242)
  name = createBus(sp, '',  name, 0,
  scope);

Error in Simulink.Bus.createObject (line
105)
      busInfo =
      createObjectFromVarStruct(sp,
      busName, fileName, format, scope);

Error in BusCreation (line 13)
busInfo =
Simulink.Bus.createObject(HallwaySensonor);

Try subclassing BHA from Simulink.IntEnumType.

    classdef BHA < Simulink.IntEnumType
    enumeration
        Stationary(0), 
        Run(1)
    end
